Use a piecewise function to express the cost in terms of the number of t-shirt purchase (13. t (5) = 14. 15. 13. a. t(s) = [200s, if 0 > > 100 d. t(s) = [200s, if 0 100 b. t(s) = (18,000, if s > 100 C. t(s) = [18,000, if s = 100 d. t(s) = [18,000, ifs 100 b. t(s) = [18,000 + 175(s - 100),if s 2 100 C. t(s) = (18,000 + 175s, if s > 100 d. t(s) = (18,000 + 175s, ifs
